GENERAL PHYSICS (PHY 203) SYLLABUS Lecture: Autumn Semester, 2012
Instructors: Professor Daniel Yaverbaum and Professor Hiroki Kitayama Lecture Instructor: Prof. Daniel Yaverbaum email addresses: [email protected] [email protected] Yaverbaum Contact Information: Phone: (212) 237-‐8980 Department: Sciences Office Hours: Room NB 05-‐66-‐22. Mondays and Wednesdays, 12:00 pm – 2:00 pm. Advance notice is always preferable. Semester Credit Hours: 4 per Semester Prerequisite: Math 241 This is the first semester of a two semester introductory course designed to provide the student with a rigorous command of the fundamental principles and problems comprising both classical and modern physics. The topics covered this semester comprise the heart of classical mechanics (kinematics, dynamics and conservation). The central theme is Galileo’s Principle of Relativity. This theme will be expressed in nine distinct but logically consistent forms: After the first three forms are introduced, each next form will frame the next chapter of material. The ultimate course purpose is to extend the predictive power of the relativity principles to the retrodictive program of modern forensic science.

Textbooks: Halliday, D., Resnick, R. & Walker, J. Fundamentals of Physics, 9th Edition. Accommodations for Students with Disabilities: Qualified students with disabilities will be provided reasonable academic accommodations if determined eligible by the Office of Accessibility Services (OAS). Prior to granting disability accommodations in this course, the instructor must receive written verification of a student’s eligibility from the OAS which is located at L66 in the new building (212-‐237-‐8031). It is the student’s responsibility to initiate contact with the office and to follow the established procedures for having the accommodation notice sent to the instructor. Statement of the College Policy on Plagiarism: Plagiarism is the presentation of someone else‘s ideas, words, or artistic, scientific, or technical work as one‘s own creation. Using the ideas or work of another is permissible only when the original author is identified. Paraphrasing and summarizing, as well as direct quotations require citations to the original source. Plagiarism may be intentional or unintentional. Lack of dishonest intent does not necessarily absolve a student of responsibility for plagiarism. It is the student‘s responsibility to recognize the difference between statements that are common knowledge (which do not require documentation) and restatements of the ideas of others. Paraphrase, summary, and direct quotation are acceptable forms of restatement, as long as the source is cited. Students who are unsure how and when to provide documentation are advised to consult with their instructors. The Library has free guides designed to help students with problems of documentation.

Learning Outcomes: Upon completion of this course, a successful student should be able to:
1) KNOWLEDGE: Know the meaning and relationships among velocity, acceleration, force, linear momentum, angular momentum and energy – as well as between instantaneous and average functions. The successful student will know Newton’s Laws of Motion and the three fundamental theorems of conservation.
2) KNOWLEDGE: The student will know that a classical application of such laws uses information in the present in order to make predictions about the future. Conversely, the student will know that this program of classical physics, when applied to the modern context of forensic science, uses information regarding the present in order to make retrodictions and discoveries regarding the past.
3) REASONING: The successful student will apply the calculus perspective on intervals
of infinitely large and infinitely small dimension to physical situations. Conversely, the successful student will derive calculus principles from analysis of the properties of motion through space and time.
4) REASONING: Relate and apply nine distinct but logically consistent forms of
Galileo’s Principle of Relativity in order to solve problems regarding kinematics, dynamics and conservation in space and time. The successful student will ultimately infer, apply and abstract how all inertial frames of reference produce distinct but equally correct measurements; s/he will reason from and to the premise that velocity is relative.
5) REASONING: The successful student will grasp that a well-‐chosen coordinate system
can make all the difference between a solution method that is merely correct and a solution method that is not only correct, but also convenient, clear and concise. Finally, the successful student will see how the laws and topics of classical physics, as well as the driving assumptions of modern forensic physics and criminalistics, can be deduced from Galileo’s Principle of Relativity.
6) PRACTICAL SKILLS: Design, build, measure, analyze and trouble-‐shoot mechanical
experiments involving inclined planes, pendulums and collisions. Use calculus and careful English in order to develop techniques for solving never-‐before-‐seen problems. Use Logger Pro and Excel software in order to gather data and relate independent to dependent variables.
7) COMMUNICATION SKILLS: Approach physics as a language, rather than as a body of
information. Through “Board Meeting” lab activities, Socratic lectures and didactic assignments intended to be handled collaboratively, the successful student’s command of quantitative material will be expressed and assessed verbally. The successful student of physics will come to regard equations as complete sentences.

Course Web-Page:
www.yaverbaum.org Consult regularly—every day—for syllabus, assignments, course information and updates. The web-‐page is used for the assignment calendar, supporting documents, exam preparation: in short, everything. Blackboard provides a link to the above site. Read the course web-‐page from left to right. The left-‐most column refers to the date of a particular class or lab—depending on which page you look at. The next column provides a brief title for the subject matter to be covered in class that day. The assignment column tells you WHAT IS DUE THAT DAY (not what is assigned that day). The last column highlights relevant principles, equations or expressions for that topic.
*** The course Web-‐Page is dynamic; it responds in real-‐time to the flow and needs
of a particular class. The advantage is that the class becomes that much more student-‐driven. The disadvantage is that students are required to be flexible. Be prepared for changes in the sequence of assignments. Check the web frequently and do not try to work many weeks in advance of assignments. Always understand that you will be tested on the correct solutions to problems that are presented on the chalkboard in class—as opposed to explanations in the text and as opposed to solutions attempted by students in response to homework assignments. *** The assignments and labs are quite often links to original documents. You are always expected to print out and bring whatever is due and relevant for a particular class meeting. You are then expected to complete all assignments on separate sheets of paper. The assignments are NOT exercises intended to review what was already discussed in lecture. They are the reverse. They are problems to consider and attempt to solve prior to lecture. Each problem set assumes that you have done the relevant reading and that you are trying your best to push yourself to the next level of problem-‐solving skill and concept application. The lecture is designed to clarify and assist with questions you have developed in your attempt to solve fresh problems. It is for this reason that you are awarded credit for thoroughness, clarity and engagement with the problems -‐-‐ rather than for accuracy of answers.

Course Policies Labs and Lab Grading.
1) Every lab activity is done in a group of four (4) people. The groups will change two (2) times in the semester. The lab-‐group change dates will be indicated on the lab web-‐page.
2) The assignment for each lab can be found on the lab web-‐page. It must be downloaded, read thoroughly and printed out prior to lab period.
3) ONE LAB REPORT PER GROUP will be submitted a week after each typical lab and graded on a 1-‐10 scale. The lab report CANNOT BE HAND-‐WRITTEN. 3) If there are special instructions for a particular lab report, they will be found in the appropriate box on the lab web-‐page. In the absence of special instructions, however, each lab write-‐up must:
a) Answer all triple-‐starred questions in complete statements of English and/or mathematics.
b) Include all relevant data tables, graphs and diagrams in Appendices and
c) Provide a full “Findings Section” – written according to the directions provided in the Lab Assignment distributed during the first day of Lab: Lab 1B: “Magnitude, Measurement and Motion”.
4) If you know in advance that you have to miss a lab, you obtain permission of your lab instructor to join another lab period. If the instructor for that lab period gives you permission, you will complete your lab work in a different lab section that week. 5) You may miss and make up exactly one lab by the method described in (4), above. 6) For any missed labs beyond the one, you will not be able to receive a grade for the associated work. 7) Instructors have the discretion not to assign a passing grade—for the entire course—to any student who is missing for more than three lab periods. 8) The average of all your weekly 10-pt lab write-ups (approximately fourteen) will count for essentially 20% of your entire Physics 203 grade. (See below for precise details.)
6
General Grading: 1) Every assessment which is scored out of 100% (one “Final Exam”, one “MidTerm Exam”, one “Quest”, one “Final Lab Grade”) is given precisely equal weight. One arithmetic mean is computed from all such assessments. This is your pre-‐assignment class average: the “Assessment Mean”. When all is said and done, these assessments will together constitute approximately 80% of your final grade (with lab being, as stated above, 20%). The rest of this formula explains how the remaining portion -‐-‐ approximately 20% -‐-‐ the “Assignment Credit”—gets factored in. The comparative weights of the Assessment Mean and the Assignment Credit will vary slightly from semester to semester, but never from student to student and never sum to anything other than 100%. This nuanced part of the system is designed to acknowledge and reward the process of growth undergone by each particular class as it pursues success on assessments. 2) Every assignment which is scored out of 4 (homeworks, labs) is added together. Every zero results in the deduction of 1 point from this total. The sum is divided by a constant weighting factor (such as 5). This weighting factor may differ from semester to semester and is dependent on the overall class dynamic, participation and calendar. 3) The result from step (2) is treated as pure percentage points and added to your Assessment Mean, described in step (1). This produces your pre-‐participation class average. 4) All points gained on written "Extra Credit" Assignments as well as 0 or 1 points of "Class Participation" points are added to your pre-‐participation class average. This class participation evaluation is based on signs of your vocal and auditory engagement in lecture, group-‐work ethic in lab and general assignment trend (e.g. a great many "4"'s have an impact that goes beyond the straight numerical sum). The sum of steps (1), (2) and (3) is your Final Class Average. 5) Please do note: The seeming complexity of the above system is in place so that your homework grade reward CONTINUAL EFFORT AND THOROUGHNESS above all else—even above accuracy of results. As a result of this system, the weighting percentages will not always be precisely 80% + 20%. From semester to semester, they fluctuate slightly around such round numbers. All four large assessments will always, however, be weighted equally. The grading weights will always, moreover, be precisely uniform from student to student and from section to lab section.
The BOTTOM GRADING LINE:
Each formal assessment is given equal weight in a straight average. The sum total of all homeworks and extra credits amount to raw points added
straight onto your class average. For example, homework itself can amount to approximately 7 extra points on your
class average. You cannot “lose” points on homework unless you literally do not submit it.
May the net force be with you.

Semester Credit Hours: 4 per Semester Prerequisite: Math 241 This is the first semester of a two semester introductory course designed to provide the student with a rigorous command of the fundamental principles and problems comprising both classical and modern physics. The topics covered this semester comprise the heart of classical mechanics (kinematics, dynamics and conservation). The central theme is Galileo’s Principle of Relativity. This theme will be expressed in nine distinct but logically consistent forms: After the first three forms are introduced, each next form will frame the next chapter of material.

Textbooks: Halliday, D., Resnick, R. & Walker, J. Fundamentals of Physics, 9th Edition. Accommodations for Students with Disabilities: Qualified students with disabilities will be provided reasonable academic accommodations if determined eligible by the Office of Accessibility Services (OAS). Prior to granting disability accommodations in this course, the instructor must receive written verification of a student’s eligibility from the OAS which is located at L66 in the new building (212-‐237-‐8031). It is the student’s responsibility to initiate contact with the office and to follow the established procedures for having the accommodation notice sent to the instructor. Statement of the College Policy on Plagiarism: Plagiarism is the presentation of someone else‘s ideas, words, or artistic, scientific, or technical work as one‘s own creation. Using the ideas or work of another is permissible only when the original author is identified. Paraphrasing and summarizing, as well as direct quotations require citations to the original source. Plagiarism may be intentional or unintentional. Lack of dishonest intent does not necessarily absolve a student of responsibility for plagiarism. It is the student‘s responsibility to recognize the difference between statements that are common knowledge (which do not require documentation) and restatements of the ideas of others. Paraphrase, summary, and direct quotation are acceptable forms of restatement, as long as the source is cited. Students who are unsure how and when to provide documentation are advised to consult with their instructors. The Library has free guides designed to help students with problems of documentation.

Learning Outcomes: Upon completion of this course, a successful student should be able to:
1) KNOWLEDGE: Know the meaning and relationships among velocity, acceleration, force, linear momentum, angular momentum and energy – as well as between instantaneous and average functions. The successful student will know Newton’s Laws of Motion and the three fundamental theorems of conservation.
2) KNOWLEDGE: The student will know that a classical application of such laws uses information in the present in order to make predictions about the future. Conversely, the student will know that this program of classical physics, when applied to the modern context of forensic science, uses information regarding the present in order to make retrodictions and discoveries regarding the past.
3) REASONING: The successful student will apply the calculus perspective on intervals
of infinitely large and infinitely small dimension to physical situations. Conversely, the successful student will derive calculus principles from analysis of the properties of motion through space and time.
4) REASONING: Relate and apply nine distinct but logically consistent forms of
Galileo’s Principle of Relativity in order to solve problems regarding kinematics, dynamics and conservation in space and time. The successful student will ultimately infer, apply and abstract how all inertial frames of reference produce distinct but equally correct measurements; s/he will reason from and to the premise that velocity is relative.
5) REASONING: The successful student will grasp that a well-‐chosen coordinate system
can make all the difference between a solution method that is merely correct and a solution method that is not only correct, but also convenient, clear and concise. Finally, the successful student will see how the laws and topics of classical physics, as well as the driving assumptions of modern forensic physics and criminalistics, can be deduced from Galileo’s Principle of Relativity.
6) PRACTICAL SKILLS: Design, build, measure, analyze and trouble-‐shoot mechanical
experiments involving inclined planes, pendulums and collisions. Use calculus and careful English in order to develop techniques for solving never-‐before-‐seen problems. Use Logger Pro and Excel software in order to gather data and relate independent to dependent variables.
7) COMMUNICATION SKILLS: Approach physics as a language, rather than as a body of
information. Through “Board Meeting” lab activities, Socratic lectures and didactic assignments intended to be handled collaboratively, the successful student’s command of quantitative material will be expressed and assessed verbally. The successful student of physics will come to regard equations as complete sentences.

www.yaverbaum.org Consult regularly—every day—for syllabus, assignments, course information and updates. The web-‐page is used for the assignment calendar, supporting documents, exam preparation: in short, everything. Blackboard provides a link to the above site. Read the course web-‐page from left to right. The left-‐most column refers to the date of a particular class or lab—depending on which page you look at. The next column provides a brief title for the subject matter to be covered in class that day. The assignment column tells you WHAT IS DUE THAT DAY (not what is assigned that day). The last column highlights relevant principles, equations or expressions for that topic.
*** The course Web-‐Page is dynamic; it responds in real-‐time to the flow and needs
of a particular class. The advantage is that the class becomes that much more student-‐driven. The disadvantage is that students are required to be flexible. Be prepared for changes in the sequence of assignments. Check the web frequently and do not try to work many weeks in advance of assignments. Always understand that you will be tested on the correct solutions to problems that are presented on the chalkboard in class—as opposed to explanations in the text and as opposed to solutions attempted by students in response to homework assignments. *** The assignments and labs are quite often links to original documents. You are always expected to print out and bring whatever is due and relevant for a particular class meeting. You are then expected to complete all assignments on separate sheets of paper. The assignments are NOT exercises intended to review what was already discussed in lecture. They are the reverse. They are problems to consider and attempt to solve prior to lecture. Each problem set assumes that you have done the relevant reading and that you are trying your best to push yourself to the next level of problem-‐solving skill and concept application. The lecture is designed to clarify and assist with questions you have developed in your attempt to solve fresh problems. It is for this reason that you are awarded credit for thoroughness, clarity and engagement with the problems -‐-‐ rather than for accuracy of answers.

Course Policies Labs and Lab Grading.
1) Every lab activity is done in a group of four (4) people. The groups will change two (2) times in the semester. The lab-‐group change dates will be indicated on the lab web-‐page.
2) The assignment for each lab can be found on the lab web-‐page. It must be downloaded, read thoroughly and printed out prior to lab period.
3) ONE LAB REPORT PER GROUP will be submitted a week after each typical lab and graded on a 1-‐10 scale. The lab report CANNOT BE HAND-‐WRITTEN. 3) If there are special instructions for a particular lab report, they will be found in the appropriate box on the lab web-‐page. In the absence of special instructions, however, each lab write-‐up must:
a) Answer all triple-‐starred questions in complete statements of English and/or mathematics.
b) Include all relevant data tables, graphs and diagrams in Appendices and
c) Provide a full “Findings Section” – written according to the directions provided in the Lab Assignment distributed during the first day of Lab: Lab 1B: “Magnitude, Measurement and Motion”.
4) If you know in advance that you have to miss a lab, you obtain permission of your lab instructor to join another lab period. If the instructor for that lab period gives you permission, you will complete your lab work in a different lab section that week. 5) You may miss and make up exactly one lab by the method described in (4), above. 6) For any missed labs beyond the one, you will not be able to receive a grade for the associated work. 7) Instructors have the discretion not to assign a passing grade—for the entire course—to any student who is missing for more than three lab periods. 8) The average of all your weekly 10-pt lab write-ups (approximately fourteen) will count for essentially 20% of your entire Physics 203 grade. (See below for precise details.)
6
General Grading: 1) Every assessment which is scored out of 100% (one “Final Exam”, one “MidTerm Exam”, one “Quest”, one “Final Lab Grade”) is given precisely equal weight. One arithmetic mean is computed from all such assessments. This is your pre-‐assignment class average: the “Assessment Mean”. When all is said and done, these assessments will together constitute approximately 80% of your final grade (with lab being, as stated above, 20%). The rest of this formula explains how the remaining portion -‐-‐ approximately 20% -‐-‐ the “Assignment Credit”—gets factored in. The comparative weights of the Assessment Mean and the Assignment Credit will vary slightly from semester to semester, but never from student to student and never sum to anything other than 100%. This nuanced part of the system is designed to acknowledge and reward the process of growth undergone by each particular class as it pursues success on assessments. 2) Every assignment which is scored out of 4 (homeworks, labs) is added together. Every zero results in the deduction of 1 point from this total. The sum is divided by a constant weighting factor (such as 5). This weighting factor may differ from semester to semester and is dependent on the overall class dynamic, participation and calendar. 3) The result from step (2) is treated as pure percentage points and added to your Assessment Mean, described in step (1). This produces your pre-‐participation class average. 4) All points gained on written "Extra Credit" Assignments as well as 0 or 1 points of "Class Participation" points are added to your pre-‐participation class average. This class participation evaluation is based on signs of your vocal and auditory engagement in lecture, group-‐work ethic in lab and general assignment trend (e.g. a great many "4"'s have an impact that goes beyond the straight numerical sum). The sum of steps (1), (2) and (3) is your Final Class Average. 5) Please do note: The seeming complexity of the above system is in place so that your homework grade reward CONTINUAL EFFORT AND THOROUGHNESS above all else—even above accuracy of results. As a result of this system, the weighting percentages will not always be precisely 80% + 20%. From semester to semester, they fluctuate slightly around such round numbers. All four large assessments will always, however, be weighted equally. The grading weights will always, moreover, be precisely uniform from student to student and from section to lab section.
The BOTTOM GRADING LINE:
Each formal assessment is given equal weight in a straight average. The sum total of all homeworks and extra credits amount to raw points added
straight onto your class average. For example, homework itself can amount to approximately 7 extra points on your
class average. You cannot “lose” points on homework unless you literally do not submit it.
May the net force be with you.

Full Write Up for Lab 5:
Your object made at least 5 round-trips along an inclinedplane with friction. Submit ONE report per every HALF
LAB TABLE (four people).
Your report MUST respond fully to all the
"D" and "Q" prompts (D1 - D2 and Q1 - Q11) in the original lab assignment. It will therefore include the
following (which is provided simply as a checklist for you):
1) A fully labeled diagram of the ball/inclined plane set-up..
2) A derivation of mu for this set-up. The derivation mustinclude:
a) Free-body Diagrams,
b) Application of Newton's 2nd Law
i) First in generalized symbols (a, g, etc.),
ii) Then with particular quantities "plugged in",
c) English.
3) A conclusion as to whether the ball takes less time toascend or descend the plane. This conclusion must be
supported by the following:
a) Neat Table of Experimental Data,
b) 2 Free-Body Diagrams,
c) Application of Newton's 2nd Law
i) First in generalized symbols (g, theta, etc.),
ii) Then with particular quantities "plugged in",
c) English.
Galileo's Principle of Relativity
Form #5:
Unless acted on by a net externalforce, an object at rest stays at rest
and an object in motion stays inmotion at the same speed and in
the same direction.
